The future of energy storage: how pumped hydro storage can
How pumped hydro storage works. Pumped hydro storage uses excess electricity during off-peak hours. During this time, it pumps water from a lower reservoir to an upper reservoir. Water is released during peak demand periods. Water flows from the upper reservoir, downhill. As it moves, it passes through turbines to generate electricity.
